Since the impact is mostly annoyance (the smell) and most restaurants are either smoke-free or offer separate enclosures, why tax it at all (besides for the smell)? I am reducing my lifespan by about 8 to 10 years with smoking, sure. But why should the government force me to change that by taxing it? Why tax sugary drinks or ban or criminalize drugs other than the caffeine, nicotine and alcohol?
If the idea is to make everyone be healthy, live as long as possible and be productive for as long as possible, why not ban dangerous sports, too? I'm "the government" for my dog and I don't let him do anything dangerous or stupid, but he's a dog and we're people. With the supposed free will and agency we all like.
>But why should the government force me to change that by taxing it?
Because the government ends up paying for the medical treatment of a lot of smokers when they're older. And it's incredibly expensive. You can say you won't rely on government funds, but there's no way to actually opt out of Medicare for life or sign up to never be guaranteed stabilization when you show up at a hospital.
Nicotine is also notoriously addictive, which weakens the "my choice" argument.
>Why tax sugary drinks
That's totally a nanny state thing. Personally, I would mildly support it. But it's not a hill I'd die on.
>or ban or criminalize drugs other than the caffeine, nicotine and alcohol?
Hard drugs cause blight. People don't mind so much if they see a soda can on their street, but if they see a used needle they'll move. And again, any society with a safety net has an interest in preventing common causes of people falling into it.
>why not ban dangerous sports, too?
It hasn't proven to be a big problem at the population level. Hell, public health experts would love to have that problem, because it'd mean more people were exercising.
